What literary characters are INTjs and other alpha quadra types? Also, what roles do alpha quadra types normally play in literature? i.e. do they serve the role of the Mentor, the Trickster, the Antagonist, etc. It seems that there are generally not too many INTj protagonists or other main characters at all. Their very nature would almost always put INTjs in a natural supporting role.
As an INTj, I'm mainly interested in INTj examples, but I would still like to hear examples of other alpha quadras (ESFj, ISFp, ENTp).
